I'm finding it pretty hard to stay off the bike for even one day :-) I bought a used mountain bike off craigslist 2.5 weeks ago, and I've been riding every day since - except once when it rained all evening. It's not real hilly around here but not exactly flat either; there are plenty of up and down-grades, and a few moderate hills (guessing 50' climb in a 1/4 mile). My legs are a little sore most days, but not enough to keep me from riding, and the soreness goes away as I ride. Don't get me wrong, I'm always gassed and dripping at the end of each ride, but always ready to do it again next day.
My goals are to lose weight and improve fitness (and graduate to the big chainring on the flats!). I'm on vacation so have been riding in the mornings, but longterm will ride weekday evenings and weekend mornings.
So, are rest days important or useful for fitness, or should I just ride whenever I feel like it? Thanks!
